Nitrogen suspension

ABSTRACT

A PROCESS FOR THE PRODUCTION OF AN IMPROVED NITROGEN FERTILIZER SUSPENSION BY DISPERSING ATTAPULGITE CLAY AND WATER WITH A DISPERSING AGENT AND ADDING THE DISPERSED CLAY TO THE NITROGEN SOLUTION TO CAUSE THE CLAY TO GEL. THE CONCENTRATION OF CLAY IN THE DISPERSED STATE CAN BE AS HIGH AS 30 PERCENT, AND WITH A CONCENTRATION OF CLAY IN THE GEL STATE (I.E,, NITROGEN SOLUTION) OF 2 PERCENT, HIGH GEL STRENGTH CAN BE OBTAINED WITH ONLY MODERATE AGITATION. THE PRODUCTS ARE USEFUL IN MAKING MIXED HIGH-NITROGEN SUSPENSIONS THAT ALSO CONTAIN PHOSPHORUS AND POTASSIUM BY SIMPLY BLENDING THE BASE NITROGEN SUSPENSION WITH PHOSPHATE BASE SUSPENSION AND SOLID POTASSIUM CHLORIDE.
